After the construction of its wastewater treatment plants, the City of Quebec began to implement overflow control in wet weather to ultimately meet the effluent discharge objectives, i.e. no more than two overflows per summer season in the St. Lawrence River and no more than four in the St-Charles River.

As part of its on-going efforts to reduce combined sewer overflows, the Louisville & Jefferson County Metropolitan Sewer District (MSD) has pioneered the implementation of “intelligent real time control” (RTC) in the United States to operate and manage its complex sewer network.

InfoWorks CS has been used to evaluate the potential of Real Time Control (RTC) to meet complex pollution control requirements for wastewater systems in two cities - Ottawa, the capital of Canada, and Bordeaux in France.

A Real Time Control (RTC) Feasibility Study concluded that CSO control requirements for the City of Ottawa could be achieved through the implementation of a more efficient operating strategy at key flow regulators along the City's interceptor sewer system.
